Why are industrial Prefabricated Steel Chimneys so tall?
Because the higher the chimney, the more the hot atmosphere of the chimney, the greater the total buoyancy force it is subjected to, the greater the pressure generated by the buoyancy, the stronger the smoke.
If you only make the chimney bigger but not taller, the buoyancy of the smoke will also increase, and in proportion to the increased cross-sectional area. Pressure = pressure/force area, the pressure and area are proportional to the increase, the pressure is actually unchanged, the suction of the lower part of the Stainless Steel Chimney will not become larger, this principle is related to the lift of the pump only with the vertical height of the water pipe, and the horizontal distance has nothing to do with it.
Is the higher the industrial Prefabricated Steel Chimney, the better?
The industrial prefabricated steel chimney is made into a cone only because of the necessity of construction, and the smoke exhaust effect does not have much help.
Industrial prefabricated Boiler Chimney is not to do the higher the better, the chimney has an optimal height, according to the exhaust volume and chimney caliber of the equipment to determine, when the exhaust volume and caliber is certain, the chimney is higher than the certain height, and then do high is meaningless.
This is also the height of the chimney has an impact on the smoke exhaust effect, but the most important is not the height of the chimney, but the chimney structure, the important thing is that the chimney should be made into a conical small upper and large lower, so that the pressure inside the chimney is much greater than the pressure outside the chimney, so that the smoke exhaust effect of the chimney is better, industrial prefabricated steel chimney is built higher,
Can be approximated to a better temperature gradient, the thermal expansion of the atmosphere rise results better.
